Android Arduino Bluetooth Control Station Apps

This Android Arduino Bluetooth Appis a modular program that I have developed with an Android and Arduino wireless connectivity via a Bluetooth. The controller application which can be uploaded to your android phone can turn on and off any appliances in your house. It can even start your car's ignition wirelessly. However, before we go into the details how these things are possible, let us first learn the basics of the project. I assumed that you are already familiar with the arduino environment. If not, you can start here with my 10 basic arduino projects.

First, we need the following hardware or materials:

1 Arduino R3 Uno

1 resistor

1 bluetooth HC-05

1 led

1 9v battery

connecting wires

1 breadboard

1 Android smartphone

Second, we assemble them using the circuit connection below. The fritzing schematic diagram, block diagram, and related photos are posted under Step 1. It would be awesome if Instructables,com can provide such option of inserting images between paragraphs on their pull down § menu. ^-^

Third, we upload our sketch into the arduino microcontroller. Various sketches are all available online. You can pick any arduino sketch of your choice. They sometimes come with schematic diagrams too. Just make sure that in the sketch, you specify "1" as On and "0" as OFF. A portion of such sketch example is shown below:

if(data == '1') //when data is equal to 1
digitalWrite(ledPin, HIGH); // then LED is ON
else if(data == '0') //when data is equal to 0
digitalWrite(ledPin, LOW); // then LED is OFF

Fourth, since this app is still on its experimental stage, you can't find it yet in the Google Play Store. However, if you are interested using this app and BE PART OF THIS PROJECT, please let me know and I will send the app to you for FREE.

The basic features of this Arduino Android Controller App are as follows:

The screenshot is identical on the video.

The green button when pressed turns On your led.

The red button when pressed turns OFF your led.

The bluetooth button lists a selection of bluetooth available in your area.

The developers name and website are posted on the screen.

The app is provided "As Is" ***(please read the disclaimer).

Finally, I challenge you on the following adventures:

use the app to control a relay

use the app to control a lamp or an electric fan

share your projects with us

NOTE: The disclaimer may sound alarming. But if you are someone who wants to learn, you would probably find discarded old phones and tablets for your projects. My disposable android phones and tablets came from my friends and relatives. Just make sure these gadgets have access to bluetooth, wifi, and accelerometer. Thrift stores and ebay are good places to find junks ;)

DISCLAIMER: *** AS IS means YOU EXPRESSLY UNDERSTAND AND AGREE THAT YOUR USE OF THE APPLICATION(APP) IS AT YOUR SOLE RISK AND IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. YOUR USE OF THE APP AND ANY MATERIAL DOWNLOADED OR OTHERWISE OBTAINED THROUGH THE SITE IS AT YOUR OWN DISCRETION AND RISK AND YOU ARE SOLELY RESPONSIBLE FOR ANY DAMAGE TO YOUR COMPUTER SYSTEM OR OTHER DEVICE OR LOSS OF DATA THAT RESULTS FROM SUCH USE. THE APP WAS ONLY TESTED ON SAMSUNG GALAXY S5 SM-G900A AND ANDROID SOPHIX TABLET MODEL NO: TAB 730G AS EMULATOR. THE APP MIGHT NOT WORK WITH ALL OTHER SMARTPHONES AND TABLETS.

There are actually other ways we can make our appliances smart aside from using bluetooth connectivity. I will post some of them here later on like how to control them remotely through the internet, your own website, via a wifi, an ethernet, a TV remote control, your computer monitor, your keyboard, your mouse, your iphone, an ipad, and even with your voice. The key factor here is how you harness a signal. Thanks for dropping by ;)
